0BE8hex (BUS FAIL)
0BE9hex (BUS FAIL)
0BEAhex (BUS FAIL)
0BF0hex (BUS FAIL)
Meaning
A serious error occurred causing the bus system to be switched off. When checking the current config-
uration, the diagnostic algorithm detected errors but could not locate the precise error location. This
indicates that the error cause always occurs for a short time only. The error rate can be very high.
Cause
The error occurs due to
– installation errors,
– a defective INTERBUS device.
Remedy
Check your system for:
– missing or incorrect shielding of the bus cables (connectors),
– missing or incorrect grounding/equipotential bonding,
– poor connections in the connector (loose contact, dry joint),
– cable breaks in remote and local bus cabling,
– voltage dips on the communication voltage supply of the remote bus devices.

Add_Error_Info —
Meaning The “Control_Device_Function” (0714hex) service could not be executed.
Cause Fatal error.
Remedy
Repeat the service if the controller board is in the RUN or ACTIVE state. If diagnostics is active, you
must wait for the result. Then, the indicated bus error specifies the error location.
Add_Error_Info —
Meaning
The data transmission was temporarily interrupted. As a result, the controller board reset all outputs
and stopped data transmission. The display shows the INTERBUS device number. The error can be
found
– in the preceding bus segment of a local bus,
– in the preceding bus segment of a ST compact station,
– in the bus segments of a preceding remote bus branch (e.g., installation remote bus), or
– in the bus segment of the indicated INTERBUS device.
Cause
– Voltage reset of an INTERBUS device in the specified area.
– Cable break in the specified bus segment.
– The bridge (RBST or LBST) in the connector for the outgoing bus is defective for a device in the
specified area.
Add_Error_Info INTERBUS device number (Segment. Position) of the INTERBUS device.
